REGRESSIVE ORTHOGONAL FEM EXPERIMENTAL ANALYSIS OF BOLT-SPRAY PARAMETERS AND ITS APPLICATION
锚喷参数的回归正交有限元试验分析及其应用实例

Regressive orthogonal experimental analysis method commonly used in experimental organization and experimental data process is introduced into numerical simulation and the quadratic surface relation between supporting parameters and stability index is given according to the optimization of the bolt-spray supporting parameters in 1# driving-station of Nanfen Ferrous Mine. This kind of method provides a theoretical basis to the stability analysis of underground opening and gives reference to actual engineering.
